Chapter 5 Troubleshooting Plug-in Modules
This chapter tells you how to troubleshoot problems that come from faults within the plug-in
modules or the associated circuitry within the rest of the instrument. The modules use visual
indications, error messages, and INOP messages to indicate a fault. All references to the Agilent
Model V24/V26 also refer to the Agilent Model V24C/V26C and Model V24CT/V26CTunless
specifically stated.
See “Procedure Overview” on page 5-2 for a more detailed overview.

This chapter shows you how to:
• Recognize a properly operating Plug-in Module.
• Identify symptoms of improper operation of the Plug-in Modules.
• Use any symptoms or indications to identify a fault as being in the Plug-in Modules.
• Further isolate faults down to field-replaceable assemblies.
&RQFHSWV
This chapter uses visual indications, Inops, error messages and other operational symptoms to
help you diagnose problems with the Agilent Plug-in Modules. Symptoms have been grouped
based on the measurement performed by the Plug-in Module.
Each troubleshooting section contains procedures for isolating faults based on the symptoms, any
supporting theory as to why you are being told to do a certain procedure, and any additional
rationale that will help you to isolate faults.
• ,QRSV – Inops are messages displayed on the screen when the V24/V26 cannot measure or
process signals properly. This could be due to patient-related or equipment-related problems.
This section deals only with those Inops which are equipment related.
• 7DVN:LQGRZ – The task window is an operating level of the V24/V26 which allows you to
make changes or adjustments to the parameters or screen displays, or to perform procedures.
Each parameter has a series of task windows which can be accessed by pressing the setup key
on the parameter module. This section uses the task windows for each parameter to check for
error messages.
